Thanks for your photos. Based on what I see here, you have either our S380-34 or S385-34, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match. 
Comparison of the S380 and S385 balance shoes.

Sure, if you refer to the chart on the S380-34 store page then you have two options: either the 3340, which carries 23 through 28 pounds, or the 3350, which carries 28 through 32 pounds. Since your old stamp is 33-5, I personally would go with the 3350. They're technically the same stamp. Ultimately, though, the choice is yours. |
